If the timing isn't advanced enough, it will not allow a FULL burn of the intake charge by the time the exhaust valve opens. This will cause the car to feel SLUGGISH and it will actually continue burning while it exits out the exhaust. This gives you EXTREMELY high Exhaust Gas Temps (headers can GLOW red hot). As for the cam, yeah it can cause SOME problems but its usually idle surging and bucking while trying to cruise. You really should (depending on how aggressive you cam is) be able to get it to hold an idle and be driveable. You REALLY DO need to bump your timing to AT LEAST 10 degrees. You'll be amazed at what it can do for you. If the car continues to run like complete shit, you probably have another problem. You want to get the car running as close to "right" as possible before you take it in for a tune. It will save you and your tuner a great deal of pain and time (and you money). I would, advance the timing to 10 degrees to start with, set your TPS voltage, and finally set your idle. Disconnect the battery to clear out the computer. Hook it back up and go from there.</blockquote>
